I’d reversed some magic said to make disappear (6)
I believe the answer is:
dispel
'make disappear' is the definition.
(I've seen this before)
'i'd reversed some magic said' is the wordplay.
'reversed' shows that the letters should be reversed in order.
'some magic' becomes 'spell' (I've seen this before).
'said' shows a homophone (sound like).
'spell' sounds like 'spel'.
'id' backwards is 'di'.
'di'+'spel'='DISPEL'
'to' is the link.
(Other definitions for dispel that I've seen before include "Drive away and scatter" , "Lisped (anag)" , "'Dissipate, clear away (6)'" , "Cause to vanish" , "Banish, drive away" .)
